Abstract
The citrus brown mite Eutetranychus orientalis (Klein), is known as one of the most significant pests in citrus growing areas worldwide. It has recently caused outbreaks in the Mediterranean region of Türkiye. This study aimed to determine the resistance levels of E. orientalis populations between 2020 and 2021 collected from 9 commercial citrus orchards in Adana province against 5 different acaricides, in order to determine whether the observed population outbreak was due to acaricide resistance. The resistance ratios were changed between 1.67 and 2.50, 1.00–2.53, 1.85–3.68, 1.30–2.65, and 1.93–3.13-fold for abamectin, etoxazole, fenbutatin oxide, pyridaben, and spirodiclofen, respectively. The enzyme activity levels of carboxylesterase, glutathione S-transferase, and cytochrome P450 monooxygenase ranged between 1.00 and 1.13, 1.02–1.52, and 0.94–1.72-fold, respectively. As a result of the resistance study carried out for the first time on this species in Türkiye, the resistance ratios were determined to be low for E. orientalis against acaricides. Although the current resistance rates were low, certain populations exhibited a noteworthy surge in enzyme activities when compared to the susceptible population. Based on these findings, it was concluded that by implementing an appropriate resistance management strategy using acaricides with different modes of action, it is possible to prevent potential resistance development and use these acaricides effectively on this spider mite species for many years through rotation.
期刊介绍:
The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics:
-Abiotic damage-
Agronomic control methods-
Assessment of pest and disease damage-
Molecular methods for the detection and assessment of pests and diseases-
Biological control-
Biorational pesticides-
Control of animal pests of world crops-
Control of diseases of crop plants caused by microorganisms-
Control of weeds and integrated management-
Economic considerations-
Effects of plant growth regulators-
Environmental benefits of reduced pesticide use-
Environmental effects of pesticides-
Epidemiology of pests and diseases in relation to control-
GM Crops, and genetic engineering applications-
Importance and control of postharvest crop losses-
Integrated control-
Interrelationships and compatibility among different control strategies-
Invasive species as they relate to implications for crop protection-
Pesticide application methods-
Pest management-
Phytobiomes for pest and disease control-
Resistance management-
Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
